In his article in the "Zeitschrift für Umweltrecht," Nils Meyer-Ohlendorf (Ecologic Institute) analyzes what consequences the Treaty establishing a Constitution for Europe would have for environmental policy. This treaty was signed in 2004 but did not come into force as it was not ratified. The author focuses on the institutional architecture of the European Union, which would undergo some changes due to the treaty.

Specifically, he examines how the treaty strengthens or weakens the political positions of the European Council, the Council of Ministers, the Commission, and the Parliament. As a conclusion, the author makes clear that the treaty is meant to be a compromise, but definitely provides improved opportunities for environmental policy making.
